IMPROVEMENT IN HYDROCARBON- STQVES.'

Specification forming part of Letters Patent No. 177,334, dated May 16, 1876 application tiled October 4, 1875. I

stove which can safely and easily be heated by the combustion of a hydrocarbon or oil in a similar manner to that in common use in illuminating-lamps.

The invention consists of the following devices: The Vessel or chamber containing the oil or hydrocarbon is submerged in water, so as to always keep the said oil vessel or chamber cool, and thereby free from explosive or other accident. The water-vessel is covered with a perforated metal plate, which forms the base of the hot-air cylinder, on the top of which the culinary or other vessels to be heated are placed. Vertical tubes .or flues are placed in the hot-air cylinder in such positions as to act as chimneys for the burners. Mica windows are placed in the sides of these flues or chimneys in such positions as to enable the operator to observe the flame of the burner and to regulate the same as circumstances may require.

The invention will be readily understood by reference to the accompanying drawings, of which Figure 1 is partly an elevation and partly a vertical section of the improved stove. Fig. 2 is partly a plan and partly a section of the same. In this view the half of the top plate only is removed, so as to disclose the construction of the hot-air cylinder and the flues or chimneys. Fig. 3 is a sectional plan of the stove, taken just below the top plate of the water-chamber, and showing a part of the top plate of the oil vessel or reservoir broken out.

The base of the stove consists of a vessel,

A, resting, for convenience, on short legs an This vessel is intended to contain water, and has a top plate, A, which is preferably made of cast metal, and strong enough to support all the parts of the stove which are above it.

ing in thesaid plate being nearly'equal in area to the sectional area of the hot-air cylinder 0, which rests upon it. Ooncentrically arranged around this central opening is a series of perforations, a through which atmospheric air passes down into the top part of the vessel A, and thence up through the hot-' air cylinder and its chimneys.

The reservoir or vessel B, in which the oil or hydrocarbon is put for use in this'stove, is placed within the vessel A, and the bottom of the vessel A may likewise constitute the support for the bottom of the vessel B, and there will be an intervening chamber, B, between the sides of the vessel-B and its inclosingvessel A, and the sides of the vessel A will extend up one or two inches (more or less) above the top of the vessel B. While in use the annular chamber B will be filled with wa-' ter, and water will also cover the top of the vessel B, which said vessel and its contained fluid will thereby be always kept at a low temperature, and accident from the ignition or explosion of the oil or hydrocarbon will thus be rendered impossible by this water covthe vessel B, and the wick used to conduct the oil from B to the flame is operated in the usual manner of illuminating-lamps. The rollers for moving the wicks up and down are inclosed in casings or housings E, and are operated by the thumb-wheels F, the stems f of which pass through tubes E, that are attached tightly to the ends of the housings E, and pass through the side of the vessel A. Care must be taken to have all of the parts of D E E that lie within the water-way of A perfectly watertight, so as to prevent the leakage of the water either into the vessel B or outside of A.

The hot-air cylinder 0 is preferably built of sheet metal, and is hinged to its base-plate A by the hinge 0 at the backside of the stove, so as to permit the top parts of the stove to be tipped back out of the way of trimming the wicks, or for other purposes. A finely-perfw rated diaphragm, G, covers the central open ing of the base-plate A! below the hot air cylinder, for the purpose of properly controlling the air-currents that pass up from the chamber of A into the hot-air cylinder. A diaphragm,H, within the hot-air cylinder 0, and near its base, is fixed, by riveting or otherwise, to the sides of the said cylinder- Portions of this diaphragm are formed into conical flamecaps h, for controlling and confining the flame within its proper limits in a manner similar to that in commonuse in illuminating-lamps.

Above the diaphragms, H tubes or chimneys I confine the hot gases and products of combustion from the flames of the burnerswithin proper limits for: the efficient action: of the burners. These tubes. or chimneys I extend,

from the diaphragm H tothe top of the hot- 3 air cylinder, and arepreferably made of sheet metal. The shell of. the hot-air cylinder. 0 forms one sideof each of these ohimneys,,aud

, in this side, whichiis common to boththe cylapertures portions of the metal. of. thechim l hey-plates are extended, which said portions are bent over in the form of grooves k, as in j Figs. 1 and 2, for the reception of the mica. plates that are to formthe windows. 1

plates of the chimneys Iand plate L, and reflected thencebackuponthehot gases passing through and about these parts, will be quite sufficient to consume all of the smoke, and there will, in consequence, be no emission of unpleasant odors from imperfect. combus-i tion. The topsurface of the plate L is provided with ridges I, that keep thevvesscls placed thereond'rom obstructing the openings;

in the said plate.

Having described my invention, I claimtop. plate A and hot-air cylinder 0, hinged at c to plate A,and top perforated plateL, all

arranged and connected together substantially as-and for the purpose setforth...
